What are the motifs in Blood Rites by Jim Butcher?

Morals are very important in the story. For Harry Dresden, it is obvious that the morals that he adheres to go along with the sense of right and wrong that he has developed. He believes that women and children should not be mistreated. When he sees children being held as hostages by the Black Court vampires, he becomes outraged. He realizes that the vampires are monsters but it is still more than he can tolerate. We see Harry's outrage again when Emma is killed. Not only is she a woman, but Harry cannot stop himself from thinking about the children that she was raising on her own. He knows that now those children are orphans and this sickens him as much as anything else.
